Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full behavioral burden. It discloses that the tool browses blueprint data and provides pagination defaults (limit default 25, max 100), which is useful. However, it does not explicitly state that the operation is read-only, whether authentication is needed, or anything about error behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single compact sentence plus a parenthetical. It is front-loaded with the core purpose and contains no wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a two-parameter list tool with no output schema, the description is mostly adequate: it names the resource, returned fields, and limit bounds. But it lacks sibling differentiation and precisely explained pagination semantics, and it does not explicitly confirm read-only behavior.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate. It mentions 'offset/limit (default 25, max 100),' but this is ambiguous: default 25 applies only to limit, while offset defaults to 0 and allows up to 1,000,000. The description does not explain offset's meaning or how pagination works, leaving the schema to convey only types and limits.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states a specific verb and resource: 'Browse Tech Lab blueprints.' It also enumerates the data returned (costs, descriptions, effects, unlock status), which helps an agent understand the tool's scope. However, it does not differentiate this tool from sibling listing tools like library_list or workshop_list.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Only the word 'Browse' implies a read/list operation. There is no explicit guidance on when to use this tool versus alternatives, no exclusions, and no prerequisites. An agent must infer its usage from the tool name and siblings.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
